Problems solved by technology

Generally, the thread tightening method is used to compress and expand the rubber sealing ring to seal the nozzles of the water chamber of the intercooler. However, the actual pressure test process shows that the clamping efficiency of the plug head is low, and the rubber sealing ring is easily damaged, and the service life is low.

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] The invention can be widely used in product sealing performance inspection. According to the embodiment of the present invention, the externally inflatable sealing plug adopts the working principle of pneumatic piston, and compresses the plug body of the silicone ring by pneumatically driving the piston body to realize fast locking and tightening of the outer diameter of the pipe joint of the sealing product. The clamping is firm and reliable, and the labor intensity is greatly reduced.

[0022] The external inflatable sealing plug mainly includes: the plug body 3, the inflatable piston 2, the sealing plug seat 6, and the sealing rubber ring 7; it is characterized in that: Figure 1-2 As shown, the inflatable piston 2 is coaxially nested in the plug body 3 to form a piston assembly, and a set horizontal gap is left between the plug body...

Abstract

The invention discloses an external-lock inflatable-type sealing plug, mainly comprising chock plug body, pneumatic piston, sealing plug seat and sealing rubber gasket; the coaxially sleeved pneumatic piston inside the chock plug body consists of piston element, and horizontal clearance is left between the chock plug body and vertical end face of pneumatic piston; pipe joint is set on the chock plug body which connects the horizontal clearance between the chock plug body and pneumatic piston; the pneumatic piston is set as the squeezed sealing rubber gasket according to inflation, and the sealing rubber gasket quickly locks the external wall of tightened pipe joint when being squeezed to realize the clamping. The plug is directed installed on the external diameter of product pipe joint,adopts the pneumatic piston-type operating principle and squeezes the rubber gasket chock plug body through inflation with simple structure, convenient clamping and reliable fixation, so as to make operators fast complete the compressing and test operation with less efforts and labor intensity largely reduced.

Description

technical field [0001] The invention relates to the cooling system manufacturing industry, in particular to an outer-embracing inflatable sealing plug. Background technique [0002] Automobile radiators and intercooler assemblies need to be checked for airtightness after manufacture. Since the pressure test pressure of the intercooler is relatively high, the diameter of the air inlet and outlet is generally relatively large. Therefore, the design of the nozzle sealing plug is very important. The essential. Generally, the thread tightening method is used to compress and expand the rubber sealing ring to seal the nozzles of the intercooler water chamber. However, the actual pressure test process shows that the clamping efficiency of the plug is low, and the rubber sealing ring is easily damaged and has a low service life. [0003] How to realize rapid and efficient sealing of each nozzle of the workpiece is a technical problem to be solved. Contents of the invention [000...
